I don't believe you is a fine and fitting answer to people saying men can be women and vice-versa.
If someone comes out of the womb with CAH, do you assign their sex based on genetics or on the phenotype? I will pay you the respect of Having Done Your Own Research on the subject of genderdysphoria, including the phenotypes, genotypes and the possible mismatches. And the association with hypothalamus differences, of which you are obviously aware.
(Hint: I am trapping you, be careful with what precedent you create with the answer :>)
